January is National Radon Action Month. Don’t get me wrong, radon wasn’t discovered last year. But over the last few years, it has become on of the most common Portland real estate inspections buyers have and one that often yields results that need attention. Radon is not isolated to one part of town. We had results over 4.0pCi/l in every quadrant of Portland last year. Ideally the test runs for about 72 hours in an undisturbed environment. You can see in the chart where doors may have been opened while the test was running. The test and system were done by Alpha Environmental.
We typically see mitigation systems cost between $1800 and $2200. I wrote this post back in September:
The general recommendation is that any home testing over 4.0 pCi/l should have radon mitigated as it is the second leading cause of lung cancer behind smoking.
